Adding CONFIDENTIAL or DRAFT to the footer of every PDF page is faster and cleaner than using a watermark — it sits neatly in the footer margin and does not obscure content.
Navigate to the Header & Footer tool in any browser.
In the footer center field, type CONFIDENTIAL. Set the font size to 9–10pt in a red or dark color. Optionally add page numbers to the right zone at the same time.
Tip: Using the footer instead of a watermark keeps CONFIDENTIAL visible without obscuring any document content — ideal for legal and business documents.
Click Apply to All Pages. Every page footer displays CONFIDENTIAL consistently.
Footer is better for readability — it does not obscure content. Watermark is more visually prominent. Use footer for working documents, watermark for distributed copies.
